From: Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars
a, b Age-[Fe/H] distributions of the local disc stars at high-\({{{{\rm{z}}}}}_{\max }\) and low-\({{{{\rm{z}}}}}_{\max }\) regions, according to the division in Fig. 1a. c, d Age-[O/Fe] distributions of the local disc stars at high-\({{{{\rm{z}}}}}_{\max }\) and low-\({{{{\rm{z}}}}}_{\max }\) regions. The red dashed box indicates the young O-rich stars. a Probability distribution of stellar age p(τ∣[Fe/H]), normalised to the peak value for each [Fe/H], for local disc stars at high-\({{{{\rm{z}}}}}_{\max }\) region. b Similar to (a) but for local disc stars at low-\({{{{\rm{z}}}}}_{\max }\) region. c Probability distribution of stellar age p(τ∣[O/Fe]), normalised to the peak value for each [O/Fe], for local disc stars at high-\({{{{\rm{z}}}}}_{\max }\) region. d Similar to (c) but for local disc stars at low-\({{{{\rm{z}}}}}_{\max }\) region.
